Branched This new proprietary power
supply topology eliminates “power sags” during low frequency
reproduction by rapidly increasing the duty cycle, stabilizing the
power supply and allowing it to deliver the power required when
reproducing wide band frequencies. Also, greater reserve gate power
is stored for low voltage conditions that occur during extreme condi-
tions.
Apex Current Topology) Reduces power
supply stress by 50%. Typical designs degrade the stereo image
due to phase reversal of even-order harmonic distortion that occurs
between the inverted channels. In the STACT design, inversion is
done at the power amplifier drive stage. Since the fully symmetrical
power amplifier produces no even-harmonic distortion itself and all
preamplifier circuitry is run completely in-phase, no even harmonic
distortion phase reversal occurs.
Protection Topology provides three types of protection:
Output protection against short circuits or improper loads
2. Ground fault detection: Shuts down the amplifier when a signifi-
cant voltage
fluctuation occurs between electrical (turn-on
lead) and battery ground.
3. Thermal Protection: Puts the amplifier into thermal rollback or
shuts the amplifier down in extreme thermal conditions.
Fully Balanced Inputs for professional-quality performance and
noise cancellation. The DIN plug carries signal information
for Left and Right channels, audio ground, and 15 Vdc to operate
the Soundstream BLT BLT4 Balanced Line Transmitters.
Harmonic Bass Alignment The 2nd and 3rd order harmonic peaks
are critically aligned to fundamental peaks at mid and low frequen-
cies. This produces tighter, more accurate bass reproduction.
Drive Delay II Amplifier section powers up 2 to 3 seconds after
the power supply eliminating turn-on pops. Turn off process is
reversed: Amplifier section turns off first, followed by the power
Output Clipping Indicators indicate clipping on the output stage of
the amplifier. Monitoring the clipping indicators allows the user to
achieve maximum Sound Pressure Level without clipping the
amplifier.

Dynamically Optimized Power Power grid is evenly
distributed between primary and secondary power supplies, provid-
ing greater dynamics and improved RF filtering.
All transistors are ideally located and sandwiched
between the circuit board and the to provide cool efficient
amplifier operation.
Differentially Balance RCA Input eliminates ground loop related
noise in the audio.
Flexible Dual Input Level Control allows 300 to 5 V input
sensitivity. Separate Left and Right level controls allow user to
optimize system level control.
Symmetrical Discrete Balanced Class A Drive Boards
adjust for linear performance while driving low impedance loads.
Removable Front Spoiler Allows for stealth installation of RCA,
Balanced Line, Speaker and Power wiring.
